Problem with button “Deny” in Attestation Workflows.

When we deny an attestation approval, the product shows the next error:

We have check if the product doesn’t have the required dll (ATT.CompositionApi.dll), and we have check if the script has any error, but it compiles normally.


Error executing script ‘VI_AttestationCase_GetRemoveMembershipActions’.
Could not load file or assembly ‘ATT.CompositionApi, Version=,Culture=neutral,…’ or one of its dependencies. The system cannot find the file specified.

Can you please, provide us, any solution for this error?


Thanks in advance.
